    What's the switch combination for the third BIOS? Leave switch one at default and push switch 2 up?

    I see, thanks for the clarification, Sajin. I guess the triple BIOS advertisement was another shot in the foot then.

    If you select the secondary BIOS and somehow it gets corrupted then switch back to Primary BIOS how would you fix the secondary BIOS if card won't boot or work properly with the secondary BIOS?

    You would need to boot into windows using the primary then set the switch to the secondary while inside windows and flash it while inside windows.

    What so these switches/bios actually do? Is there better performance etc.... Really would like to know as I'm fixing to do a review over at the egg and a couple of other places. Best to get the facts from a reliable place, plus couldn't find much on the net about it. Thanks.

    So you can actually hot-switch this safely on the fly?

    No, you can't hot-switch the vBIOS on the fly. A reboot is necessary for the card to boot off the secondary if you switched it from the primary while inside windows.

    Sorry, I meant when you're booted from a good one, can you safely hot-switch to the bad one to reflash?

    Increased fan speeds & higher power limits I believe.

    nice, i guess i never thought to look on mine
    so the second bios is supposed to up the power limits? am i correct in that understanding of this information?

    Yes, the card could become a paperweight if flashed incorrectly.

    How unfortunate.In that case I don't think I'm going to do it given the fact that I am not very confident that I can do it right,anyway thanks for the quick replay.Wish you the best

    If I understand what you are saying correctly, Sajin, then when I boot up with the stock second BIOS (without flashing it!), GPU-Z should display a different BIOS version than the primary BIOS, right?
    Any more information on this BIOS?

    2 = Enables / Disables BIOS write protection.




    I think I may be doing something wrong then as I get the same results/report from the DOS window regardless of which position #2 is in. For the record, which direction (up or down) disables write protection?  Thanks...this has been a great forum for a n00b to get acquainted with these cards!
